Up-n-Atom Burger

Up-n-Atom Burger is a fast-food restaurant chain in the HD Universe and appears in Los Santos in Grand Theft Auto V. The first restaurant opened in 1950 in Los Santos. The company is a parody of California-based In-N-Out Burger. Their slogan is "Once it pings, eat like kings", implying their food is microwave-cooked. This is also a reference to the bells used in some fast-food restaurants to notify an order is ready. The restaurant can not be entered by the player.
